F. 1 maths

Recall that odds in favor of an event E=P(E occurs) : P(E does not occur) and
odds against an event E =P(E does not occur) : P(E occurs)

Solution:
P( passing next Math test)=63%
=> P(not passing next Math test)=1-63%=37%
=> odds in favor of passing next math test = 63%:37%=63:37

odds in favor, in the other word, probability
